I’m away in my other van and my mate is running our Velle to keep her fresh.
Got this from him;
Can anyone assist with this issue developed on a 2009 BNZ 2.5 diesel.
It’s struggling with mid range boost and pauses before full boost kicks in on high revs.
During that pause the glow plug light starts flashing which is P2237 (O2 sensor bank 1,sensor 1).
The code clears on restart as it’s not present.
Eventually the EML comes on also which is P2279 (inlake air leak) which is present.
I’ve checked over all turbo hoses, intercooler and vacuum hoses and all looks ok.
I’m assuming given the turbo is working, the waste gates are operating prematurely hence the pause which is indicating high o2 levels in the exhaust gases hence P2237.
I’ve read MAP, PCD diaphragms or N75 are problematic.
Any ideas would be very much appreciated.
Ps moo valve was new a couple years back.
